@John_Beranek okay i’ve got something new for you.
Lets get rid of the old patched code first:
yum reinstall -y tfm-rubygem-katello
and then re-run through the same operations as before:
cd /opt/theforeman/tfm/root/usr/share/gems/gems/katello-3.15.0.1
wget https://github.com/Katello/katello/pull/8689.patch
patch -p1 < 8689.patch
foreman-rake db:migrate
systemctl restart httpd dynflow*
